Changing Misty Brightdawn Origin for Ninearlia

I have to changed Misty's Origin for the Main Ninearlia Universe Series, In main Ninearlia Universe, Misty will be adoptive daughter of Brandonshy and Fluttershy. I love Alphabittle, but with Bridlewood not existing in the main universe, it doesn't work as perfect, but also Opaline not existing either, this was my option. So what do you wanted think about this in the comments below?
